A physician, identified as Craig Spencer, who Worked for Doctors Without Borders and treated patients in Guinea, has tested positive for the virus at Bellevue Hospital in New York City, according to the New York Post. Spencer was rushed to Bellevue Hospital and placed in isolation, after showing symptoms of the illness, including a 103-degree fever. A further test will be performed by the CDC to confirm the finding.

New York Mayor Bill de Blasio said at a news conference earlier, that Spencer came in contact with very few people and those people are being located.
